Metabolic safety of the etonogestrel contraceptive implant in healthy women over a 3-year period.

Objective: To ascertain whether placement of the etonogestrel contraceptive implant induces significant changes in carbohydrate and lipid metabolism, as reflected by metabolic parameters, in healthy women.

Study Design: Prospective cohort study of 213 healthy patients who received etonogestrel implants. Weight, BMI, blood pressure and a comprehensive metabolic profile were assessed at baseline, 1, 2 and 3 years.

Women with primary ovarian insufficiency have lower bone mineral density.

The aim of the present study was to assess the prevalence of osteoporosis in a sample of 32 patients with spontaneous primary ovarian insufficiency (POI) in comparison to reference groups of 25 pre- and 55 postmenopausal women. Hip (lumbar) and spinal bone mineral density (BMD) measurements were performed by dual-energy X-ray absorptiometry in the three groups. The median age of POI patients at the time of diagnosis was 35 years (interquartile range: 27-37 years).

Screening of follicle-stimulating hormone receptor gene in women with premature ovarian failure in southern Brazil and associations with phenotype.

We investigated the presence of mutations/polymorphisms in the FSH receptor (FSHR) gene and their association with phenotype in women with premature ovarian failure (POF) in southern Brazil. Clinical and hormonal variables were determined in 36 46,XX women with primary or secondary amenorrhea before the age of 40 yr, FSH >40 IU/l and ovarian failure. DNA was isolated from peripheral leukocytes.

[Premature ovarian failure: present aspects].

Premature ovarian failure occurs in approximately 1:1000 women before 30 years, 1:250 by 35 years and 1:100 by the age of 40. It is characterized by primary or secondary amenorrhea and cannot be considered as definitive because spontaneous conception may occur in 5 to 10% of cases. In 95% of cases, premature ovarian failure is sporadic.

Endometrial response to a cyclic regimen of percutaneous 17beta-estradiol and low-dose vaginal micronized progesterone in women with mild-to-moderate hypertension.

Endometrial response to natural estradiol and low-dose vaginal progesterone replacement therapy was evaluated in 20 postmenopausal women with chronic, mild-to-moderate hypertension. A cyclic hormone replacement therapy (HRT) regimen was used (21/28 days) with percutaneous estradiol (1.5 mg/day) and vaginal micronized progesterone (100 mg/day).
